T470s Skylake ThunderBolt 3 PCIe lanes

Q:T470s Skylake ThunderBolt 3 PCIe lanes

Hello to everyone, Can someone answer definetely on how many PCIe lanes T470s 20JTS1FQ06 (Skylake i7-6600U) are available to the Thunderbolt3 connector? Although I have checked everywhere in psref and many sites, I get only ambiguous answers. 50% say 2 and 50% say 4 lanes. Thank you

Hi, I'm interested in adding a 256MB m2 PCIe SSD drive however i would like to find out the lane speed limit/bandwidth for my specific laptop. It's a ENVY Notebook 15-as016tu with a i7 6500 . i don't want to buy an expensive drive that my laptop cannot use to it's fullest output.

Does anyone know how many PCIexpresslanes are allocated to the thunderbolt 3 port on the Yoga 730 15". I have gotten in touch with lenovo technical support, but they had no idea. I did see where the 720 is thought to have 2 lanes, but I am not sure if that is the same on the 730. Thanks for any info!

Hello.. just bought a 2nd gen Yoga x1.. i7600u/8gb/256gb/OLED for $1100 on the outlet website. Couple questions if anyone knows.. is the Thunderbolt port 2 or 4 lanes? I'd like to use a razer core if it's 4. Also can I charge using my Samsung usb C charger?

I'm very confused by all the conflicting info surrounding this laptop. User reports and Lenovo schematics are all over the place. Can someone help me set the record straight? What are the lane configurations for the below? Should I have any expectation of newer motherboards for Whiskey Lake? What would the extra 4 lanes even be used for? 13 inchKaby Lake-R CPU (i5-8250U, i7-8550U)Whiskey Lake CPU (i5-8265U, i7-8565U)15 inchKaby Lake-R CPU (i5-8250U, i7-8550U)Whiskey Lake CPU (i5-8265U, i7-8565U)Kaby Lake-R CPU (i5-8250U, i7-8550U) with GTX 1050Whiskey Lake CPU (i5-8265U, i7-8565U) with GTX 1050 (customized build only)

I am trying to purchase two samsung 960 pro 2TB model,and bit curious whether it will work or not.I am using P70 with xeon 1575Mv5, and in the Intel homepage,there seems to be maximum 16 lanes are supported by CPU.It seems to me that those 16 lanes are totally occupied by the graphic card. As P70 was configurable with two PCIe-nvme SSDs, I guess it will use two x4 PCIe ports.apparantly this configuration is using more PCIe lane than it supports.. Therefore I think I have to figure out following questions before making the decision for purchasing new SSDs..Is P70 have some kind of way to use more PCIe lanes?How much PCIe lanes P70 is capable to use?If, somehow, my configuration is using more lanes than supported, what happens?(Will it operate, but with crippled performance,or blow off?Or.. I am totally misunderstanding the concept of capability of PCIe lanes, and the system will operate without any problem?) Thank you in advance.

If you want to use an eGPU you need 4 lanes of PCIexpress otherwise the loss is too great for it to be worth it. But you only lose about 10% of the original power if you have 4 lanes of PCIexpress through Tuhunderbolt 3. So, what do the 13" and 15" models offer for the number of PCIexpress lanes?

I've been studying for my A+ certification lately, and I've run into a little bump where I'm having some confusion.

According to what I read, the highest PCIe multiplier currently is x16, as there currently can be no more than 20 PCIe lanes. If this is true, though, how is it possible to have motherboard chipsets with a 16x and 6 1x's (which by my math should make 22 lanes)? I'm really confused, any help here would be awesome.

Thinkpad X1 Extreme Platform Specifications:https://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad%20X1%20Extreme/ThinkPad_X1_Extreme_Platfo... On the above link, Lenove states this device only supports [email protected] on DP output of Thunderbolt 3 port, which indicates each Thunderbolt 3 port of this device supports only 2 PCI-E lanes. But on the other hand, there are some articles claims that X1 Extreme supports 4 PCI-E lanes on each Thunderbolt 3 port. Which is true?

Hello, I'm considering buying a ThinkPad. Here are the models available: t460s - i5-6300u, 8gb, 256gb SSD, FHD non-touch t470s - i5-6300u, 8gb, 256gb NVMe, FHD non-touch Since they have almost the same design and weight, do you think t470s with faster ssd and usb-c is worth the 200$ higher price? What about battery life? I'm not considering KabyLake t470s as I need Windows 7, and the similar model with i5-7200u costs additional 150$.

Hi all (Dell - mods - would especially appreciate your response):I am considering buying a Samsung 950 SSD for my XPS 13 9350. The machine currently has 128GB SATA SSD.Does anyone know - and I called and chatted with Dell Tech Support and it seems like they are not too familiar with these concepts - whether these machines support 2 or 4 lanes PCIe for the SSD?One Dell rep on the phone told me 2 lanes. A Dell chat support told me 4 lanes. Neither seemed too confident in their answer and one referred me to a Wikipedia page as a source.I know the 9350 supports PCIe connections. Just trying to figure out if it is 4 or 2 since that will impact the speed - and decision on what SSD to buy. From what I see the machine also supports NVMe - but if anyone knows this for sure please let me know. Thanks!

hello, I have a ThinkPad X1 Yoga (2nd Gen) 20JD004UUS, Intel i7-7500U. I want to buy an external GPU and connect it via Intel® Thunderbolt? 3 portthat I know it has.The question is - how many PCIe lanes does it has? x4? maybe x8 or x16?This will determine the throuput ans subsequently the model of GPU to buy. https://www3.lenovo.com/us/en/laptops/thinkpad/thinkpad-x/Thinkpad-X1-Yoga-2nd-Gen/p/22TP2TXX12Yhttps://www.laptoparena.net/lenovo/lenovo-thinkpad-x1-yoga-(2nd-gen)-2673 Thanks :-)

this is for someone from Dell to answer.I just bought an 8th-gen Dell XPS 13". it has the Core i7-8550U and i ordered one with 16GB LPDDR3 1866MHz memory, 256gb PCIe SSD .my question: for M.2 slot, how many PCIe lanes are available? are they PCIe 3.0?i am wondering in case i decide to upgrade the SSD at a later time and I don't want to buy an SSD that is faster than the bandwidth available to the M.2 slot.bonus question: what Intel chipset does the motherboard use?thanks.

A:Dell XPS 13" 8th-gen: what kind and how many PCIe lanes on M.2 ?

If you already have this system, use a utility like HWInfo64 to expose the information you're looking for. The 9350 and 9360 both had 4-lane M.2 slots, and I'm fairly certain they were PCIe 3.0 since that's been around for a while now, so I imagine the new version will be the same -- in fact when I last checked Dell's site, even the version with an 8th gen Core CPU was being called a 9360. That said, that doesn't mean your SSDs will always perform at their max. I installed a Samsung 960 Evo into a friend's 9360 and I think it got something like 1.4 GB/s read, regardless of whether I used the native Microsoft or Samsung NVMe driver (BIOS set to AHCI mode to bypass Intel RST). Reviews of the 960 Evo have indicated that they can reach around 3.1 GB/s reads in certain systems, although I found several other reviews with numbers closer to mine, so I don't consider my result anomalous. It's possible that having a U Series CPU (low-power) is creating a bottleneck at such high SSD speeds given that the reviews I saw with 3 GB/s+ read speeds were typically performed on desktops with a top-end K series CPU.

Hi, the PSREF document for the T480 mentions that the M.2. 2280 SSD slot has 4 PCIe lanes (see http://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad%20T480/ThinkPad_T480_Platform_Specificatio...). However the german site campuspoint.de who sells campus models of the T480 states that the M.2 2280 SSD slot in this model (unlike the T480s) is limited to 2 PCIe lanes, just as on the previous T470. I wanted to be sure and asked them, and here is their reply: We were stumbling over the same point in the PSREF. The difference to the former Models like T470 and T570 made us suspicious, since the new models use a very similar Adapter. So, we made a simple test. We took a T580 with a Samsung PM981 SSD, which should be able of up to 3200 Mb/s of read performance and made a simple benchmark. Our test showed a read performance of roughly 1800 Mb/s at max. This is about the same score as we had with the T470 and T570 Models and just slightly under what is theoretically possible with two PCIe Lanes. It looks like Lenovo just didn?t mention the restriction by the Adapter. This has nothing to do with Campus Models or not. The Campus Models use the same parts as used in other Thinkpad models. As you mentioned the T480s doesn?t have this issue. Can Lenovo confirm there is a mistake in the PSREF of the T480 and T580 with respect to the number of lanes for the M.2 2280 SSD slot?

I wasn't able to find this in the User/Maintenance guide, or anywhere else. I presume the M.2 Storage slot on this system isn't fed by just one lane. That would restrict NVMe SSDs to about the same speed as Sata SSDs. Thanks in advance for any information anyone can provide or point me to.

All, How many PCIe lanes for the internal NVMe M2 slot, that used the 2.4 HDD/SDD enclosure, has and what is the max. transfer speed.What to know if it worth while to install a Samsung EVO 970 or PRO 970 and fully utilize their speed. Thanks

A:Windows 10, Skylake & Thunderbolt 3 bring the most compelling reasons to upgrade in a long while

Sorry.No matter what others think about W10.THIS is not a reason for an upgrade, if one has a choice.Stay away from -remote host,-cloud centered OS.Take your hardware and host your stuff by yourself.Do not accept crippled OS (what unfortunaly OS X (since making iCloud a default location for files, belongs to).

One feature of Intel's chipsets that hasn't changed much over the past few years, even for the enthusiast X-series chips, is the amount and speed of the PCI Express lanes provided. Most chipsets, including the latest Z97 and X99 models,...

HiI just would like a description and confirmation on what the following options do under the Thunderbolt 3 dock in the Bios for this series laptop I tested the option "No security" and this seems to bypass the authentication pop up when logged into Windows when plugging in the Thunderbolt 3 dock. So essentially it enables network ethernet connection to work straight away Can someone tell me what the other options do?

Hi All I have been crawling through these forums and Google in general, it seems a lot of people have similar issues. I run a T470s, I use a Startech USB-C to HDMI adaptor allowing me to connecto to 2 external monitors. I have done for many months and all was fine. I recently ran system update and found multiple drivers needed updating, I ran this and since I cannot use my external monitors. Thunderbolt software is up to date, as per screenshot it doesnt show the controller version or details in lower half. Device Manager doesnt show the controller at all (even hidden devices). I have tried:uninstall/reinstall of TB SWrunning the firmware update tool but that just says 'No Active Controller' in the system.I have tried reinstalling every Intel driver availablethe BIOS was updated by System Update previouslyI have checked the BIOS settings and everything is enabled I found a system restore point from a few days ago which I think is before this started, rolling back to that allows the TB3 SW to show the controller version and a device showing in Device Manager but my monitors still dont work. A further reboot without changing anything takes me back to 'None' controller version and nothing in Device Manager. Open to the idea it could be my adaptor has died, I understand you sometimes need a TB3 device connected to update the FW (?) but I do not have any other devices, hoping to try my adaptor on another machine at head office next week to ...

Hi all, Before I blow $500 on this dock can anyone tell me if my t470s will work with it? I want to output 4k at 60hz to two monitors. https://www.alogic.co/alogic-thunderbolt-3-dual-display-docking-station-w-4k-power-delivery-black.ht... It uses HDMI for one of the outputs, and my monitors are thinkvision p27u-10's which have HDMI 2, so that shouldn't be a issue.

Am running a T470s with a Gigabyte eGPU. Been working fine until I upgraded to the latest BIOS 1.31 the other day, and now it no longer works. The small fain of the eGPU will spin up but the main unit itself (main fan, lights, etc.) will not spin up at all.Thus far I have...1. Checked BIOS settings (No Security)2. Installed/reinstalled Thunderbolt software & firmware3. Downgraded BIOS to the last two versions and back4. Tested eGPU with work laptop & it functions as expectedI'm running Windows 10 but I believe that the issue is unrelated to Windows 10. The reason is, is that beforehand, when the laptop first boots and is still in the BIOS phase, the eGPU used to fire up immediately (lights & main fan). But I cannot even get that, which tells me the issue is not Windows 10 related.Any other suggestions before I go open a support ticket with Lenovo? I'm still under warranty at least.

Hi Everybody, Hope i'll find help here. I spent hours to make my T470s (20HF) working with external display (LG 27UD88-W) via USB-C. I bought 40Gbps Belkin cable at price of gold.I updated all my drivers (lastest intel 620, all stuff i've found on Lenovo, Installed the thunderbolt software/drivers from Lenovo 17.3.74.400, BIOS etc).Well it looks like every thing is up to date. But I still don't have the ThunderBolt controller displayed in windows devides manager... And of course my 4K display is not working.When plugin USB-C C cable, the ext monitor detect something is hapenning, and Thinkpad is trying to use external display, but he doesn't success. The laptop screen blinks, CPU running high, something loops. Well what's going wrong here ?Thanks for your help

Hi everyone, I recently installed a HP Thunderbolt-2 PCIe 1-port I/O Card (F3F43AA) into my HP. I did all the connections inside and outside the box. I've installed the Win10 drivers. Now the problem I'm having is that my OWC Thunderbay 4 is not connecting properly. (https://eshop.macsales.com/item/OWC/TB2IVKIT0GB/) How can I troubleshoot the Thunderbolt card? I believe it's the card that is the issue... not the enclosure. Any suggstions would be so helpful. Thank you in advance!-Richard

Hello! I recently bought two HP thunderbolt 2 PCIe Cards for my workstation (not an HP) and it seems either they were not correctly installed or I still need to download some kind of drivers or Bios. I would really apreciate any comment on how to get them working. My workstation is a Supermicro Superserver 7048GR-TR and I used the only 2 free slots (10 and 11) to install the cards. I Have the instructive to install them in an HP Z820,Z620,Z420,OR Z230 which are similar HP models to my Supermicro Workstation, and the card comes with a set of different cables to adapt depending on which Z model you have. The problem here is that in my workstation I have to leave that port of the card unconnected since there is no equivalent port in the mother board to connect it to. Any thoughts?Cheers!

Hello, Can I successfully install a HP Thunderbolt-2 PCIe 1-port I/O Card F3F43AA into a slot OTHER than Slot 5?I have an HP Z820 w/s and have successfully used my Thunderbolt-2 card, installed in PCIe Slot 5. AVID has just supplied me with a PCIe card that also requires installation in Slot 5. This is a conflict they are unable to resolve, so far.Might I be able to move my Thunderbolt-2 card to another slot? I wish to connect to an external RAID or other drive.

It's not clear to me what 'Wake by Thunderbolt' (hereafter WbT) does and whether or not it's required for 'Wake On LAN' (hereafter WOL). In the T470s and T480s user guides, there's no mention that WbT is required for WOL so I'm thinking it's not. But then again, since Ethernet is in the dock itself, and seeing how there are controls for PXE, I could see how it might be required. ReferencesT470s User GuideT480s User Guide

Hi,I myself own an XPS 15 9550 and noticed that I was not getting the full Thunderbolt 3 speedover it's Thunderbolt 3 port. I expected speeds around 2700MB/s, because of the overhead withthe theoretical gross speed of 3870MB/s, but I only ever got 1400MB/s out of it.I did some digging and found out that none of the XPS notebooks with Thunderbolt 3 are evenable to achieve the full TB3 speeds, because they are only connected with two PCI Express lanes (x2.3).You can read more about this on the following links:Dell Subreddit PostChipset Digging on Forum

Thunderbolt 3 and the promised speeds were the MAIN REASON I even bought this notebook.I feel very cheated here.

I am trying to use a 3rd party external GPU enclosure that attaches via thunderbolt, and when attached, I got the message pop-up that external GPU support was not enabled by the vendor, and as such the device will likely not work? Has Dell locked the Latitude 7480 down to no external GPU support?

I just got my X1 Extreme yesterday. I updated the BIOS to 1.15 and also updated other drivers. The one pending thing is the Thunderbolt firmware update utility. The first pop-up says "do not connect any Thunderbolt device", but then a second pop-up right before the firmware update says "connect at least one Thunderbolt device. I cancelled the update for now due to the conflicting pop-up messages. Note - I do not have any Thunderbolt devices connected to my X1E laptop. Can I upgrade Thunderbolt firmware safely with no Thunderbolt devices connected, or?

Because I didn't liked USB 3.0 ethernet chipsets and USB-based ethernet cannot bear some network-intensive tasks, I wanted to use PCIe-based Thunderbolt ethernet controller on my XPS 15 9550. As there is no Thunderbolt 3 "PCIe" ethernet adapter (except docks), I chose to buy Apple Thunderbolt 3 to 2 adapter and Thunderbolt 2-based ethernet adapter.I plugged it into the XPS 15 9550 (tested with BIOS 1.1.19, 1.2.14, 1.2.16 and latest Thunderbolt firmware with NVM version 16), and the PCIe device did not pop up. Instead, only USB billboard device is appearing saying that "Alternate Mode configuration not attempted". Both Windows 10 and Ubuntu 16.10 failed to detect the device. I moved this configuration to MSI GS63 laptop, and it detected ethernet controller successfully (that laptop utilizing NVM firmware version 18).It seems that other vendors are affected with lower NVM firmware version involving setup with Thunderbolt adapter: see the case of Lenovo too. Do you have planned Thunderbolt NVM firmware update for XPS 15 9550? Looks like XPS 13 9360 is using newer Thunderbolt NVM firmware version, though.

Yesterday I installed a Samsung 950 pro 256gb m2 pcie nvme ssd into a Dell E7270Older configuration was with a sandisk regular sata 3 ssd. After replacement did a bios reset twice, once factory reset, once custom. (I left sata on ahci.)I chose to install windows 10 pro x64 by using the uefi/gpt methode. Legacy options off.Installation went without a problem. Afterwards I installed the Samsung nvme driver 1.4.7.17.Also the Samsung magician software. It reports a link speed 8Gbps (is ok), link width 16 Gbps (should be 32?) .Is there a way to change the pcie link width from 2x to 4x? I thought this ultrabook did support x4.E7270 i5 6300U, 16gb ddr4, Samsung 950 pro 256comment would be appreciated :-) Thanks in advance!

Hello guys, I was wondering if the XPG SX6000Pro 256GB PCIe 3D NAND PCIe Gen3x4 M.2 2280 NVMe 1.3 R/W up to 2100/1500MB/s SSD will work with my y520 IKBM. and if there is an extra slot for memory.thank you.
